Should i speak with the adjuster supervisor?

I have been in contact with the insurance adjuster and independent adjuster for a third party injury claim. I sent a big packet including all medical bills, records, other supporting documents and a letter stating why their insured is at fault and so on. The independent adjuster had no problem that i semt them in myself. He told me i can forward everything to him if i wanted to. Now i recently spoke to the adjuster at the insurance co, and she said that it have no value to claim and she cant evaluate it because i didnt sign the form for them to get medical bills and etc. This isnt right it is legal for me to send in my own records. Should i call the supervisor?
